Serena has a square-shaped garden. She wants to put a fence around the outside of the garden. One side of the garden is 8 feet long. How many feet of fence will she need?

P = 4s

P = 4 * 8

P = ?

No.

Multiply 4 times 8.

To find out how many feet of fence Serena will need, we need to find the perimeter of the square-shaped garden. Since all sides of a square are equal, and we know that one side is 8 feet long, we can multiply this length by 4 to get the total perimeter.

So, Serena will need 8 feet + 8 feet + 8 feet + 8 feet = 32 feet of fence in total.

Therefore, Serena will need 32 feet of fence.
